EDWIN GRIFFITHS, OF CHESTER, WEST VIRGINIA.

CAGE FOR PICKLING METAL PLATES.

Specification of Letters Patent.

Application filed August 8, 1917. Serial No. 185,055.

To all whom it may concern:

Be it known that I, EDWIN GRIFFITHS, of Chester, in the county of Hancock and State of West Virginia, have invented a new and useful Improvement in Cages for Pickling Metal Plates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical sectional view of apparatus illustrating my invention; Fig. 2 is a side elevation showing the apparatus in position to discharge the plates; Fig. 3 is a plan View of half of the bottom of the cage; Fig. lis an end elevation, and Fig. 5 is a side elevation of the same.

In the manufacture of what is known as tin plate, the iron or steel plates as they come from the rolls have to be pickled to remove grease and scale to impart a clean smooth surface to the plate. The object of my invention is to provide a cage for carrying the plates to and from the pickling bath, into which cage, and from which, the plates may be readily placed and removed.

In the drawings 2 represents the cage which consists of a metal frame having a bottom formed in two sections 3 and 4,

which are hinged to the cage at the ends thereof, the sections being divisible at the middle. Journaled in bearings secured to the side bars 5 of the bottom are rolls 6,

on which the edges of the plates to be.

pickled rest, and extending from longitudinal bars 7, which extend from one side bar 5 to the other, between the rolls 6, are upright posts 8. This forms a cage having a bottom the two sections of which are tiltable upwardly from the middle toward the ends; having rollers for supporting the plates on their edges at right angles to the axes of the rollers; and having vertical posts.

which hold the plates in an upright position. The operation is as follows: The plates to be pickled are placed on the rollers 6,

Copies of this patent may be obtained for five eentseaeh, by addressing the Gominiss ioner of Patents,

resting on their edges, and between theposts 8. The cage carrying the plates I is then placed in the pickling vat, where it is allowed to remain until the plates-are pickled, after which the cage is lifted from the vat and placed on a stand9 through the bottom of which a vertical plunger 10 is elevated to raise the meeting sides of the tiltingv sections 3 and 4 and thereby tilt the sections sufficiently to cause the plates in the cage to travel on the rollers 6 and to be discharged into an open box or case 11, which box rests on a roller 12 journaled in the inclined bot- Patented Sept..3, 1918.

tom of the buggy 13. When the plates are delivered to the box 11, the weight of the plates causes the box to travel on the roller 12 to and against the stop 14. As shown in V the drawings, the plunger 10 is operated by a lever 15 and link 16. From the foregoing description the advantages of' my invention may be appreciated by those skilled in the art.

Having thus described my invention, what I claim and desire to secure by Letters Patent is c 1. A cage for pickling metal plates having a bottom formed in sections pivoted to the outer portions of the frame, rollers journaled in said sections, and upright posts, the sections of the bottom being capable of receiving an upwardly tilting movement.

2. A cage for pickling metal plates 'having a bottomformed in sections pivoted to the outer portions of the frame, the sections 'of the bottom being capable of receiving an upwardly tilting movement, in combination with a vertical plunger and lever adapted toraise the sections to tilt the same.

In testimony whereof, I have'hereunto set my hand. I I
